MadelineProto Example (now async for huge speed and parallelism!):

if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');
$MadelineProto->start();

$Bool = $MadelineProto->messages->setBotPrecheckoutResults(['success' => Bool, 'query_id' => long, 'error' => 'string', ]);

Or, if you're into Lua:

Bool = messages.setBotPrecheckoutResults({success=Bool, query_id=long, error='string', })
